Make a minor update msi that fixes the issue and get your users (or write a stub that) runs it from the command line with the repair and recache msi options.

Subject: Re: [WiX-users] How to remove custom application with malformed uninstall package You have a couple of options: Firstly, there's the MSI Cleanup Utility http://gallery.technet.microsoft.com/MSI-cleanup-utility-3889c8db This is an old tool which I thought had been retired, but it's come in very handy. Note that this will not perform any uninstall operations or any MSI logic at all. It basically hunts round the MSI registry for evidence of your install and removes it. Any of your own registry entries or files will not be removed. But it's good for cleaning up a broken install. Secondly, there's it's younger sibling, in the form of a FixIt troubleshooter: http://support.microsoft.com/mats/Program_Install_and_Uninstall This will scan for installs it thinks have problems, ask you a few questions, then do pretty much the same as the cleanup utility above, though it's supposed to do a more intelligent job. Thirdly, you can find the appropriate MSI in the c:\windows\installer cache, remove the offending action from the sequence using orca.exe and then try to uninstall it again. Lastly, I know some people who swear by CCleaner for this kind of thing: http://www.piriform.com/ccleaner Hope one of those suggestions helps.
